So quite !!!

I Love my windmill air conditioner. Not only does it look great but it’s powerful and oh so quiet. If you’re looking for a new air conditioner look no further!!!!

My Favorite Purchase (Ever!)

I've now used this AC for my bedroom in two separate moves. Both places I lived in would get unbearably hot over summer, and the Windmill AC saved my life - it's my favorite thing I own! I especially love the timer feature, allowing me to fall asleep comfortably (I also love the sound of the AC to fall asleep to), while not having to have the AC run throughout the night. I also have a dog and could check on the app while I was at work to see if the room was getting too hot, then turn on the AC so my dog wouldn't overheat.My first bedroom was rather large and the AC was able to cool it down within minutes. My second room was smaller, and I never needed to run the AC on high because the lower settings are so powerful. I would use this AC no matter how it looked, but it doesn't hurt that it's pleasing to the eyes. Finally, it's super easy to install and uninstall. I've had it for 5 years now, installing and uninstalling it each season (it takes a matter of minutes with my boyfriend and me) and have taken it on two moves, and it's held up great!

Money well invested!

I purchased 2 units. I have a 2 story home. I live in the Pacific Northwest so summers can get toasty and if you have never been up this way... 85% of the homes DO NOT have central ACI did some research and when I saw Windmill's product I was on board from the the get go. From the sleek design and size and the options to customize the looks.To my surprise the units come with their installation kit and just like the box says... installation was a Breeze! So if you are on the fence on getting a window unit... I highly suggest this product. Support small business!

Happy Windmill Customer, x4!

We recently switched all of our air conditioners to Windmill. They are so quiet, you don’t even know they’re on. Even on the high setting, it is nothing compared to other units. I enjoy them and they have helped cool our older home down in the summer. We will definitely purchase other windmills in the future, if needed!

A life saver

This is such a top notch air conditioner it’s unbelievable. The app makes it so convenient to use and turn on before I’m getting ready for bed or whenever I get home. Also the air blowing up instead of out genuinely cools the room so much more. I have a very large master suite and it cools it down so well. Plus the look of it?? Amazing. It’s so seamless and not the bulky and ugly window units you are used to.

Great air conditioner!

Bought a Windmill for our bedroom window to augment a dying central air system this past summer. Very happy with our choice!Installation is easy. If you've installed other air conditioners, you can definitely install a Windmill. If you haven't installed an air conditioner before, the Windmill is very approachable and the very clear instructions take any guesswork out of the process.This is a design-forward product, and I do appreciate the thought that was invested in its appearance. Certainly more attractive than most window air conditioners, both inside the house and outside. Not an eyesore!It's straightforward to operate, and I found the smart/connected functionality to be quite welcome and useful. Overall, it's worth the investment, easy to live with, and even easier to recommend!

Love our Windmill!

I ordered the Windmill for our living room to replace an old, very loud window air conditioner. The Windmill attracted me because it was advertised as being very quiet. The advertisement wasn't wrong. It was such a hot summer that we ran the Windmill unit a lot, and it cooled the space well with little noise. I will be replacing the few other window units with more Windmills as needed.

We live in Oregon & till recent years never needed air conditioning. We own a small motel near Crater Lake.We now have 3 Windmill AC units in our house/office alone. The are easy to install and operate.They keep us, our guests, and most importantly our fur babies super comfortable all summer.We will always come back to this brand. Thanks much!

Solid AC unit

I live in 100 year old building with 4 exposures (n,s,e,w). We have to rely on AC units to keep our apt cool. We bought 3 units and it has seriously helped. The units are understated, not obnoxiously loud and best of all the app woes quite well to turn the units on before we get home. It's so easy to program them to turn on and off that it almost feels like central air because when we come home it's actually cool! I had an issue with one unit and the customer service was also great. Stand out product and buying experience.

Great product

The design is simplistic so it doesn't stand out like a sore thumb in my bedrooms and living room. - The low humming as opposed to louder clanky sounds of the other typical brands is the selling point for me! I also like that I'm able to program it from my phone so on those hot days I can have the house cooled down before getting home. - customer service was also very accommodating and punctual. Overall I'm very happy with my purchase.
